I found a piece of a plastic straw in my son's bathroom after he'd had several boys over while we were out of town. Obviously, my first thought is cocaine, although the straw is larger than a normal straw and not angled at one end. And, I don't believe these boys could afford the high price of cocaine. I did find that our supply of Alka-Seltzer cold medicine looked as though one or two had been taken. I'm wondering if they could have ground those up to snort, IF such a thing is done to produce some sort of high. OR, the cut-up straw could be totally innocent, but I don't think so... Any ideas?
